I live in the frozen tundra of Rexburg, ID. Our winters are what you call "freaking cold." We just bought a brand-new house and for a reason that God may judge them for, they did not put in insulated garage doors. My garage was like stepping into the frozen food section in Costco. I came across this product and liked it due to the high R-Value. I think the product is expensive for what it is, nonetheless the install was quick, easy, and doesn't look terrible! I'd recommend it 100%.
